 o
Orris root

I had a mini-crisis on Sunday afternoon while at the Cleveland markets. There was this herb stall and I was stuck between buying garlic or orris root, and I had Mum hovering around saying 'Come on! We need to get going.' So I chose the orris root on impulse.

Now I'm wondering if anyone could tell me a bit about it! In the pot, there's at least three fans of sword-like leaves, and with the largest fan, it's possible to see the rhizome easily. I've tried looking at other iris posts and it seems like only certain types of iris grow up this way in Queensland. The orris root would probably go in a position which gets morning and afternoon sun with mid-day dappled shade.

Happy gardening!

RE: Orris root

Perennial with blade-like leaves growing in a fan shape. They can reach to 75cm tall. White flower with purple streaks in spring. Rhizome has a violet scent.

Propagate by dividing clumps. The rhizome should be slightly above soil level. If starting from seed, shake seed in some dry, sharp sand, or nick carefully with a file. Sow at 18-22C for 2-4 weeks, move to ?4-+4C for 4-6 weeks, then to 5-12C for germination. Germination is irregular and can take anything from 30-545 days. Grows in most well-drained soils in sun. Requires little care.

Collect roots in the second or third year of growth. Peel and chop while soft, then dry for at least 2 years before the scent is at maximum strength. Grind to a powder. Ribbed seedpod contains 3 rows of seed.

Warning: Orris root and leaves are poisonous, and can cause allergic reactions in some people.

I live not far from Cleveland, and can assure you that orris does very well in this area. The fan-shaped clump will just get bigger and bigger and is easily divided. I've got a whole row of them at the front of my house, originating from a tiny pot like the one you bought, and they are totally neglected, and get water only when it rains - they are in full sun. They are doing beautifully, thank you. The flower is very short-lived, but very pretty, if you're quick enough to catch it.
